  • Publication number: 20250141102
    Abstract: Antennas having single or parallel printed circuit board-based feed stalks and base station antennas having such radiating elements. The single feed stalk can have two feed lines configured to feed radio frequency signals to respective dipole radiators. Each feed line can have twin ground lines on one side (primary surface) of the single feed stalk printed circuit board and a cooperating feed trace on an opposing side (opposing primary surface) that provide RF transmissions from a feed network to a dipole radiator. The twin ground lines for the first feed line can be on a different primary surface than the twin ground lines for the second feed line and one ground line of each twin line set can cross-over each other at a forward end portion of the feed stalk. The parallel feed stalk printed circuit board can provide two feed lines for a respective dual polarized radiating element.

  • Publication number: 20230395971
    Abstract: A base station antenna comprises a reflector assembly and a first radiating element having a first feed stalk and a first radiator. A base of the first feed stalk is adjacent the reflector assembly and the first radiator is adjacent a distal end of the first feed stalk. A center of the first radiator is offset from the base of the first feed stalk in a longitudinal direction that is parallel to a longitudinal axis of the base station antenna.

  • Publication number: 20230098188
    Abstract: The present application relates to an antenna assembly for a base station antenna, a base station antenna arrangement and a base station antenna. The antenna assembly has a reflector, which has a longitudinal extent, a front side and a rear side opposite the front side, where the front side is configured for radiating elements to be arranged thereon, wherein, the reflector has a first longitudinal section residing in a first plane and a second longitudinal section residing in a second plane that is adjacent to the first longitudinal section, where the first plane is rearward of the second plane. The properties of the base station antenna arrangement and the base station antenna may be improved through the antenna assembly.

  • Patent number: 11581636
    Abstract: A base station antenna comprises a plurality of columns of first radiating elements configured for operating in a first operational frequency band, each column of first radiating elements comprising a plurality of first radiating elements arranged in a longitudinal direction and an isolation wall positioned between adjacent columns of first radiating elements and extending in the longitudinal direction. The isolation wall comprises a frequency selective surface configured such that electromagnetic waves within the first operational frequency band are substantially blocked by the isolation wall.
